                   对于逻辑回归有个前提条件是数值型自变量之间不线性相关，请问对于类别型自变量是否也有相同的要求，还有数值型自变量与类别型自变量之间是否有何要求？

                   [s:12],这两天在恶补逻辑回归理论方面的内容，应该说逻辑回归最终转化为线性回归来处理，所以相应的参数检验都应该使用线性回归的内容，看来要回过去再看看线性回归。

                   请问怎样确定glm得到的logistic回归参数是否有意义呢，王斌会老师的书上有讲如果有参数没有通过检验的话可以通过setp方法进一步优化，但没有说明如何判断参数是否有通过检验。

                  </p>
                  <p>
                   Like R,  ff can handle datetime as posixct (double) and character as factors (integer).
                   <br/>
                   Unlike R, ff does not directly support character.
                   <br/>
                   Read ?levels.ff and ?ramclass.ff
